Abstract: 1,243,876. Stop mechanism for conveyers. GEO. W. KING Ltd. 1 May, 1970 [6 June, 1969], No. 28892/69. Heading B7L. A stop mechanism in a conveyer of the type having an upper track 16 supporting a drive chain provided with depending drive dogs and a lower track 12 supporting load trolleys, which trolleys are driven by engagement of depressible drive abutments mounted thereon with said drive dogs, comprises a stop member 20, slidably mounted and normally biased into an operative position by a spring 21, in which position the member engages the drive abutment of an approaching trolley to depress and disengage it from the associated drive dog. When it is required to release the trolley from the stop one arm of a pivotally mounted bellcrank lever 25 is moved into the path of the drive dogs by briefly energizing a solenoid 30, and when engaged by a drive dog, said arm rotates in an anticlockwise direction, Fig. 4, a cam roller 27, Fig. 2, provided on the underside of the other arm of said bell-crank which had previously passed freely over a pivotal dog 22 mounted on the stop member pushes the dog 22 and causes the member to retract, sliding out of engagement with, and thus releasing, the trolley drive abutment which is subsequently engaged by a drive dog. The stop member is retained in the retracted position by a plunger 34 until a rotatable arm 38 mounted on a shaft 37 is engaged by the trolley as it leaves the stop and releases the plunger allowing the stop member to assume its operative position. The plunger 34 is loaded by a spring 35 and is pivotally connected to an arm 36 fixed to the rotatable shaft 37 on the lower end of which shaft is mounted the arm 38. When the stop member is retracted the plunger engages in a recess provided in the member to retain it in a retracted position. When arm 38 is pivoted by the departing trolley the arm 36 rotates moving the plunger out of the recess and allowing the stop member to be urged into its operative position by the spring 21.

Abstract: 724,179. Suction cleaners. ELECTROLUX CORPORATION. Nov. 27, 1950. No. 28922/50. Classes 8 (1) and 8 (2). In a device for separating dust from gas e.g., a suction cleaner comprising a housing 10 Fig. 4 defining a filter compartment 23 partitioned by a filter element 30 into intake and discharge sides having an inlet 14 and an outlet 74 within the housing and through which dust-laden gas is drawn and clean gas is discharged respectively by suitable means e.g., a fan 71, a cover 16 giving access to the compartment 23 for replacement or renewal of the filter 30 is opened automatically by means e.g., a pneumaticallyoperated triggering device 250, Fig. 14, on a predetermined pressure difference between opposite sides of the filter 30 acting on a control device 200. The control device 200 comprises an upwardly biased pressure responsive diaphragm 203 open at the lower and upper sides to the dirty and clean sides of the filter bag 30 through ducts 210, 230 respectively. A duct 231 also connects the clean side of the filter 30 to the lower side of an upwardly biased diaphragm 252 through a normally closed valve 240 which is opened to allow access of vacuum to the diaphragm 252 by a solenoid armature 350 on closing of a switch 327 by movement of the diaphragm 203 on clogging of the filter 30. The diaphragm 252 acts through linkages 254 255, 89, 87, 83 and link 81, Fig. 12, to release the first of two latches 63, 62 restraining a filter ejector plate 52 subject to spring-loaded lazy tongs 53, Fig. 5, and simultaneously the diaphragm 252 acts through linkages 254, 131 to trip a latch 100 to allow the cover 16 to be opened by a spring 18 and thereon release a rocker arm 96 to open an on-off switch 310 in the fan motor circuit. On the cover 16 being fully opened, a cam 94 on parallel linkages 115 by which an inlet 15 is pivoted to the cover 16, draws a bar 92 which actuates levers 88, 84 and a link 82 to release the second latch 62 to allow the plate 52 under the influence of the tongs 53 to eject the bag 30 which is of readily disposable material e.g., porous paper; the open end thereof having been closed by a' flap valve on the withdrawal of a duct 21 secured to the inlet 15. The switch 310 may be opened and closed manually as may the cover 16 without both the bag ejector plate latches being released. In a modification using a non-disposable cloth bag, ejection is prevented on automatic opening of the cover by a projection of the bag supporting ring pushing against the upper end of a bell crank 197 Fig. 13 thereby opening a normally closed shutoff switch 321 to stop the fan motor 72. Specifications 712,233 and 724,252 are referred to.

Filed: 1962-07-27
Abstract: 1,008,039. Measuring electrically. PATENT VERWALTUNGS G.m.b.H. July 27, 1962 [Aug. 4, 1961], No. 28932/62. Heading G1N. In an arrangement for comparing two alternating voltages, for example in an angular position indicating system, the voltages are rectified, and one only of the voltages is then slightly smoothed, while the other remains unsmoothed. A coarse error voltage 1 is rectified at 5 and the higher harmonics are smoothed by capacitor 6. A reference voltage 2 is phase shifted by capacitor 12 and rectified at 11. The two voltages are then compared in flip-flop 9. As shown in Fig. 3, the slight smoothing of error voltage F<SP>1</SP>, while reference voltage V remains unsmoothed, causes the difference voltage D<SP>1</SP> to remain above the lower response limit Z of the flip-flop instead of falling below it every half cycle. A D.C. bias source 8 may be connected in the error voltage channel and a current limiter 3 may be provided.

Patent GB-843393-A (GB)
Title: Improvements in or relating to hydraulic multi valve units
IPC: F16K31/124
Filed: 1956-09-21
Abstract: 843,393. Chucks; lathe details. PRECISION INDUSTRIELLE. Sept. 21, 1956 [Oct. 3, 1955], No. 29014/56. Class 83 (3). [Also in Group XXIX] Chucks.-Chuck jaws 13 are actuated by levers 16 rocked by the plunger 15 of a fluidpressure piston 11. A pump 2 supplies fluid to a pipe 6, and with the distributer 18 in the position shown, the fluid enters a pipe 17a and acts on the left of the piston 11 to keep open the chuck jaws. When the piston reaches its extreme rightward position, the pressure rises until a pressure-controlled contact MCa causes actuation of an electromagnet EV, whereby the distributer slide 19 is lowered and directs fluid into a pipe 17b to move the piston 11 leftward and close the chuck jaws, until at the end of the stroke another pressure-controlled contact MCb is operated. In each case the fluid from the exhaust side of the jack passes to a tank 1 via a pipe 24. A pressure-regulating valve BP1 and a pressure gauge are associated with pipe 6. Turning.-The pump 2 also supplies fluid to a tool-feed device 9, comprising a piston 35. With the parts in the position shown, fluid is fed to the left of the piston 35 to retract a tool 37 via a distributer 43 and a pipe 42a. Upon energizing an electromagnet EVD, the distributer slide 49 is lowered so that fluid is directed through a pipe 42b to move the piston 35 to the left, the fluid exhausting from the other side of the piston passing through pipe 42a, a passage 44a, a pipe 45, and a bore 46b into the lower space 50b of another distributer, and thence to the tank 1 by a pipe 47b. When the tool approaches the workpiece, a cam 38 closes a contact 40 and energizes the electromagnet EVR of the other distributer, and causes lowering of the coacting slide 51, whereupon discharge through pipe 47b is prevented and the flow to the tank 1 is directed via passages 46a, 47a and a regulating valve R, whereby the rate of feed is controlled. At the end of the work-cycle, a contact 41 is operated by a cam 39 and de-energizes the electromagnets EVD, EVR, whereupon the tool 37 is retracted at maximum speed. Another pressure-regulating valve BP2 and a pressure gauge M2 are associated with pipe 7. A number of regulating valves may be arranged in cascade for sequential operation.

Abstract: 781,986. Reinforced plastic sheet material; strengthening edges. WALKER, D. W. R. Aug. 18, 1955 [Oct. 9, 1954], No. 29144/54. Classes 42 (1) and 140. A method of reinforcing an article of flexible thermoplastic sheet material at points of stress concentration where attachments are made which pass through the material, comprises the application of textile material on one or both sides of the sheet in the region of the attachment, the sheet being partly fused into the textile material, leaving the outer surface of the textile material substantially free of plastic. As shown in Figs. 1 and 2, a tarpaulin 1 is made of a flexible sheet plastic, such as polythene, and around its edge is folded a strip of hessian 2. Heat and pressure are then applied until the plastic fuses partly into the material of the hessian on each side. Brass eyelets are applied through holes punched in the composite material. The eyelets comprise a main body 3 and a closing disc 4 into which the shank of the main body is expanded. Other attachments such as hooks or handles may be riveted through the reinforced parts of the plastic in similar manner. Canvas, linen, cotton or fabrics made of synthetic fibres may be used in place of the hessian. The entire tarpaulin may be made up of two or more thicknesses of flexible plastic instead of one. The two or more layers are treated as one and become welded together where the reinforcement is applied. The sheet material of the invention may be used for tents, vehicle hoods, portable water tanks, bags or garments.

Filed: 1935-10-22
Abstract: 466,413. Knitting. HOLMES, H. H., and WILDT & CO., Ltd. Oct. 22, 1935, No. 29171. [Class 74 (ii)] A method of knitting a welt preceded by a separating course in an odd rib fabric comprises relatively shogging the needle beds to bring the needles as near as possible to a 1 x 1 rib formation, subsequently knitting the separating course and in the next one or more courses knitting tuck stitches on the needles allocated to those wales of pairs of adjacent like wales, in which laddering would normally occur. The needle layout in the embodiment shown is for 3 x 2 rib as indicated by the letters C, D in the Figure. The sequence of operations is as follows. Courses 1-4, cylinder needles knit, dial needles are inoperative. The dial is then shogged one needle space to the left. Course 5, all needles knit. Courses 6, 7, dial needles inoperative, cylinder needles knit. Course 8, all needles knit. Course 9, dial needles inoperative, left hand cylinder needle in each group of three tucks, remainder knit. Course 10, dial needles inoperative, cylinder needles knit. Separating course 11, all needles knit. Cylinder needles are now raised to clear height and lowered to cast off their stitches. Course 12, all needles knit. Course 13, as course 9. Courses 14-16 dial needles inoperative, cylinder needles knit. Course 17, as in courses 9 and 13. The dial is then shogged back to form 3 x 2 work and knitting is continued on all needles. The tuck stitches in one of each pair of plain wales which lie adjacent to one another, prevent laddering at these points. The method is applicable to any other odd-rib fabric. The next length of knitting may be started in 3 x 2 rib or may be preceded by a length of knitting approximating to a 1 x 1 rib as in courses 5-8.

Title: Improvements in or relating to the production of melamine
Filed: 1948-11-10
Abstract: Pure melamine is prepared from melamine containing caustic soluble impurities by mixing the crude melamine at an elevated temperature with an aqueous liquor containing melamine in solution, filtering off undissolved material, adding to the filtrate an alkali metal hydroxide or alkaline earth metal hydroxide, and cooling to recrystallize melamine from the solution, the amount of hydroxide added being sufficient to retain in solution at the recrystallization temperature those caustic soluble materials not removed during the filtration but not in excess of that amount which will raise the pH to 13.  Preferably the initial aqueous liquor is saturated with melamine at the recrystallization temperature, and the mother liquors from the final recrystallization are used for this purpose; in this case, the mother liquor is neutralized with acid, e.g. hydrochloric, before re-use.  The aqueous liquor may contain up to 5 per cent of an alkali or alkaline earth metal salt.  The hydroxides may be potassium, sodium, calcium or barium.  The process may be operated batch-wise or continuously and a decolourizing agent may be used. The initial crude melamine may be in the form of a slurry with water.
